10 :CHANnel<n> Commands
:CHANnel<n>:BANDwidth
(see page 798)
Command Syntax
:CHANnel<n>:BANDwidth <limit>
<limit> ::= 25E6 in NR3 format
<n> ::= 1 to (# analog channels) in NR1 format
The :CHANnel<n>:BANDwidth command sets the bandwidth limit value and turns
on bandwidth limiting (see the :CHANnel<n>:BWLimit command).
For waveforms with frequencies below the bandwidth limit, turning the bandwidth
limit on removes unwanted high frequency noise from the waveform.
Bandwidth limit also limits the trigger signal path of the channel.
While you can request any limit; the oscilloscope will choose the only bandwidth
limit available, 25 MHz.
Query Syntax
:CHANnel<n>:BANDwidth? [MAXimum]
The :CHANnel<n>:BANDwidth? query returns the current setting of the low-pass
filter.
If the bandwidth limit is off, the query returns the full bandwidth of the
oscilloscope.
When the MAXimum parameter is used, the oscilloscope's maximum possible
bandwidth is returned.
Return Format
<limit><NL>
<limit> ::= 25E6 or full bandwidth in NR3 format
